Hi there,
I semi recently came to own a junkyard k20z3 engine from a crashed Civic SI, and the shape of the inside is pretty bad. Lots of varnish, light sludge, etc. It has 110k miles on it, and lived a hard life as far as I can tell, but was cheap and runs well but it smokes a tiny bit and compression is slightly low.
I don't drive the car with this engine often, and it's a summer only car, so racking up thousands of miles is gonna take months and summer will come and go before I reach them. I'm curious, has anyone ever convinced a solvent cleaner like Kreen with an ester cleaner like Auto-RX or HPL Engine Cleaner? Did it work? Given that both are slow and gentle cleaners, maybe they could do their slow gentle thing together and make progress slightly faster?
Given that Kroil doesn't indicate Kreen as incompatible with high ester content or synthetic oils, and you could just as well run it with Redline or something like that, I don't see an obvious reason they would not play well together. That said, I'm obviously not a tribologist so I'm curious what others have to say.

P.s. I have Kreen and HPL Engine Cleaner sitting here already. If it's a seriously bad idea to combine, and I instead do them sequentially, which would go first?
